There’s a dedicated lift to take you to the second floor along which the Vault sprawls. The restaurant itself is spacious with fat leather-upholstered armchairs and low tables. Outside is a gorgeous terrace that runs along the entire length of the restaurant with the only wood-fired pizza oven in Connaught Place. But the real star seating is the five ‘vaults’ that are private dining rooms and resemble bank vaults, sturdy doors and all. Well worth it, even if you are claustrophobic (the doors do not close) as each vault has a different seating capacity, from 5 - 15.
